AT&T gives $50 credit if you upgrade your iPhone at Apple and use Next

AT&T is quietly running a Next upgrade promotion that will reward existing customers with a $50 bill credit when they trade up to a new iPhone at an Apple retail store or through Apple's online sales channels. Customers can now finance the iPhone 5c, iPhone 5s, iPhone 6, and iPhone 6 Plus through AT&T Next 12 or AT&T Next 18 plans and receive a $50 credit on their wireless bills.
